Gremlin (Graphic) API

When it comes to modeling intricate, interconnected data, the Gremlin API stands out. Ideal for applications delving into graph databases, this API provides tools to manage and traverse relationships with efficiency.

• Complex relationships: The Gremlin API is perfectly suited for applications such as social networks, recommendation systems, or any other platform requiring intricate data connections.

• Powerful query: The Gremlin query language allows for in-depth traversals, ensuring detailed insight for your graph data.

Each of these APIs illustrates Azure Cosmos DB’s commitment to providing developers with versatile tools tailored to their specific needs. As you venture deeper into your proj-ects, remember: Azure Cosmos DB’s API suite ensures that you have the right tool for the job regardless of your data model or system.

EXAM TIP

When answering questions related to Azure Storage and Cosmos DB on the exam, always consider the data type (structured versus unstructured), data access patterns (frequency, latency requirements), and scalability needs. Understanding the unique characteristics and benefits of each Azure Storage type and the Cosmos DB API can help you select the right solution for a given scenario.

Here are some examples:

• For large volumes of unstructured data such as images or videos, Azure Blob storage is commonly the go-to solution.
• When you encounter questions about globally distributed applications requiring low-latency and multiregion replication, Cosmos DB should be top of mind.
• If there’s mention of structured, non-relational data in a key-value format, think of Azure Table storage.

■■ For hierarchical data structures ideal for big data analytics, remember Azure Data Lake Storage Gen2.

By grounding your knowledge in real-world applications and distinct use cases, you’ll be better positioned to answer exam questions accurately and confidently.

Remember to revisit this tip before your exam. It will serve as a guiding principle to quickly and effectively reason through storage-related questions!
